Indigo Airlines — Was not allowed to board the flight

Address:	Chennai, Tamil Nadu, 600063
Website:	www.indigo.com

I arrived at the boarding counter by 4.35. But still, then i was allowed to board the flight. The counter person took my boarding and cancelled without even asking me anything. I was forced to take the next flight which has costed me around 13000. (Indigo flight). I am extremely dissatisfied as i am a corporate customer. The booking was done by quest2travel
